GIGABYTE GA-EP45-UD3R overclock settings

Ok i have a GA-EP45-UD3R motherboard Q6600 Core 2 Quad, OCZ DDR2 1066 RAM, Zotac GTS 250 graphics card. I have attempted an overclock of 2.66GHz but fail prime every time. My CPU overheating is not the case I have that monitored.

Could someone please help me with a solid overclock between 2.66GHz and 3.2GHz with RAM as close to 1066 as possible. Any help is appreciated. Thanks in advance.

CPU Termination ..... 1.200V*.......: << If overclocking Please set to stock, Auto overvolts this way to much. Optimal range for overclock would be 1.2-1.5 depending on Vcore, try to keep at least .1 under vcore. Auto is fine if not overclocking

CPU PLL ....1.500V*.......: << If overclocking Please set to stock, Auto overvolts this way to much. Optimal range for overclock would be 1.5-1.65. Auto is fine if not overclocking

CPU Referen. ....0.76

CPU Reference2 ,,0.800V*.......:<<< .67% Of Vtt (Termination above) Auto Will set this correctly

Re: GIGABYTE GA-EP45-UD3R overclock settings

That ram does not look to have very good timings or reviews, so I hope you have tested each stick at stock manually set settings one by one with Memtest86+ to be sure it is in working order, if not please do >>Memtest86+ - Advanced Memory Diagnostic Tool

Here is what I would advise per your given settings >>

If you would like something with ram closer to 1066 let me know and I will advise, I just gave these because I thought you may want to get 2.6 going first

DRAM Performance Control
Performance Enhance...................: [STANDARD]
Extreme Memory Profile (X.M.P.).....: Disabled
(G)MCH Frequency Latch...............: [Auto]
System Memory Multiplier ..............: 3.20B = 1040 (Or you may need to use 3.00A for 975Mhz until I can advise again) Choices with D are not going to work for you until you get close to the D Strap (400 FSB)

CPU
CPU Vcore….……….........................:1.3 << more may be needed, all up to your CPU. Keep in mind, you get less than you set and less than that at load. For a small overclock such as this manual stock voltage or a little more should work

Re: GIGABYTE GA-EP45-UD3R overclock settings

Thanks for the advice and your help.

With 8x multiplier and 333Mhz and the rest of your advised settings I got prime to run stably. Should I try and run prime again only with Memory multiplier at 3.20B instead of the 3.00A I am currently running at?
